PART 3    EXECUTION
3.1	EXAMINATION
A.	Examine surfaces, which are to receive tile.
B.	Do not proceed with work until defects or conditions which would adversely affect quality, execution and permanence of finished tile work are corrected.
C.	If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
3.2	PREPARATION
A.	Prepare surfaces in accordance with ASTM F 710 using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.
B.	Newly poured concrete must be cured 7 days before installation of moisture remediation membrane.
C.	Clean surfaces thoroughly prior to installation. Surfaces must be clean and free of dust, oil, grease paint, tar, wax, curing compound, primer, sealer, form release agent, laitance, loosely bonded topping, loose particles or any deleterious substance and debris which may prevent or reduce adhesion.
D.	Most uncoated concrete floors will only require sweeping and priming. Pre-coated or contaminated floors must be mechanically abraded to completely remove all paint, loosely bonded topping, loose particles and construction debris. Surface profile should achieve ICRI CSP #3. Surface should be vacuumed to remove loose debris.
E.	Turn off all forced ventilation and radiant heating systems and protect work against drafts during installation and for a period of at least 72 hours after completion. Use indirect auxiliary heaters to maintain the temperatures in the area at the recommended workable level. Vent temporary heater to exterior to prevent damage to surface prep work from carbon dioxide build-up.
F.	Before work commences examine the areas to be covered and report any flaw or adverse condition in writing to the Architect and Contractor.
3.3	INSTALLATION
A.	Install in accordance with manufacturer's instructions.
B.	Coordinate with finish floor installation, cover with suitable underlayment or finished floor as soon as possible.
C.	After application test the moisture vapor emission rate of the concrete per flooring manufacturer's recommendations and industry standards.
3.4	PROTECTION
A.	Protect installed products until completion of project.
B.	Touch-up, repair or replace damaged products before Substantial Completion.
